Forming blocks speed production of strain gage grids [PDF]

open access: yes, 1965
A tool is designed which facilitates the forming of wire grids used in manufacturing strain gage grids. Flattening the grid wire by a cold working process produces a stabilized grid which can be readily handled for storage or ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Reduced-Order Modeling and Stability Analysis of Grid-Following and Grid-Forming Hybrid Renewable Energy Plants

open access: yesEnergies
The control methods of energy systems can be categorized into grid-following and grid-forming types. The grid-following control method relies on grid synchronization and is prone to stability issues in weak grid conditions.

Progress in mixed Eulerian-Lagrangian finite element simulation of forming processes [PDF]

open access: yes, 1990
A review is given of a mixed Eulerian-Lagrangian finite element method for simulation of forming processes. This method permits incremental adaptation of nodal point locations independently from the actual material displacements.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Grid Forming MMC-HVDC for Enhanced Renewable Energy Integration in Interconnected Power Systems

open access: yesAdvances in Electrical and Computer Engineering
With the increasing penetration of renewable energy generation, the fluctuating power output and widespread use of power electronic devices pose significant challenges to power grid stability.

Adaptive model predictive control for grid‐forming converters to achieve smooth transition from islanded to grid‐connected mode

open access: yesIET Generation, Transmission & Distribution, 2023
One of the main capabilities of grid‐forming converters is the ability to operate in both islanded and grid‐connected modes. The grid‐forming converters work autonomously and behave as an AC voltage source when they are isolated from the bulk power ...

Strippable grid facilitates removal of grid-surfaced conical workpiece from die [PDF]

open access: yes, 1966
Female die facilitates the removal of a sheet metal structure from a die used for explosive forming of the metal. The female die consists of a smooth conical frustum made of fiber glass with a cured epoxy-resin surface on which a molded grid pattern made

Formal Aspects of Grid Brokering

open access: yes, 2009
Coordination in distributed environments, like Grids, involves selecting the most appropriate services, resources or compositions to carry out the planned activities.

Spatially-unresolved SED fitting can underestimate galaxy masses: a solution to the missing mass problem [PDF]

open access: yes, 2018
We perform spatially-resolved, pixel-by-pixel SED fitting on galaxies up to $z\sim2.5$ in the Hubble Extreme Deep Field (XDF). Comparing stellar mass estimates from spatially resolved and spatially unresolved photometry we find that unresolved masses can
